Self study of sophomore physics, how to learn sophomore physics well

I was in the freshman physics competition class and was passing by.

We finished the high school content very quickly, the coach spoke quickly, and we usually had very little class time, so we basically relied on self-study. The accuracy rate must be improved, the competition is not tolerant of negligent errors, in addition, the formal physics competition can use a calculator, we usually have a calculator in one hand, and those who do not have it will be scolded. The curriculum should be done step by step, according to 1 up and 2 up and down, because dealing with many problems requires a kind of synthesis.

As for the question of books, I'm like this, the books I bought online, "Dragon Gate Topics" are quite good, you can buy all the books on high school physics. As for the method, the foundation must be solid, although our usual practice questions are all semi-finals or the last few questions of the college entrance examination, but this kind of big question can quickly make people find their own problems. Help to the end, then deal with the problem, when looking at the problem, figure out the physical process, you must be clear about what happened, what has changed, and then you will examine the equation of each process, and solving the equation is a mathematical problem.

There is also a physical model, such as a light rod model, etc., to remember, the synthesis of the model is a problem! Finally, there should be no multiple-choice questions in the competition (there should be no multiple-choice questions in the competition, 7 big questions in three hours), don't write the calculation process, list the main equations and instructions, and then write "simultaneous solution" or something, the calculation process is on scratch paper, don't forget that you can use a calculator.

In fact, there is no problem, I studied mechanics in the first year of high school, I studied electromagnetism in the second year of high school, and there are simple harmonic motions of momentum and the like, I think as long as I understand the concept, it is OK to do a few more questions, don't be too careful about the correct rate, there is a difference in the difficulty of the question, this is not a measurement standard, the most important thing is to have a feeling, it is enough to explain it clearly if you are wrong, I am in my third year of high school, and I also studied physics.

It is possible to buy high school physics books on the basics that can be self-taught or to consolidate the basics.

In the second year of high school, if you are afraid that you will not be able to pick it up, you can buy a few reference books that introduce more about the content of the textbook and take a look, sometimes the reference book is better than the textbook.

I have also participated in physics competitions, and I recommend that you buy 'five-year college entrance examination, three-year simulation', which includes exercises for all the knowledge points of high school, which can help you systematically test the effect of self-study. You'd better read the textbook first and understand the above knowledge points before you do the questions. I wish you success!

It's too slow, we have to speed up the progress and learn CSP and modern times first.

I'm only in the fifth grade of elementary school, but I can give my opinion. Go to the newsstand to see if there is a [Science World] book for sale, it must be helpful to you, it talks a lot of scientific knowledge, it is read by some adults, and sometimes you can have some fun by reading it. My dad can't even understand it!

Hee-hee).

Wang Houxiong's book "Textbook Explanation" physics is very good, and I also use this, especially for self-study, it is a little difficult, and the national volume is full. But there are a lot of them.

I don't know which province you're from, I'm from Henan, and the sophomore physics is all in one volume. You can go to Xinhua Books and Television. I hope you pay attention to the textbook.

70% of the physics in the second year of high school is electromagnetism, and it is impossible to directly study the second year of high school.

1. Learn more, observe more, and think more.

In fact, high school physics is about some theorems of things in nature, these are many things around us that contain these truths, there is physics everywhere in life, for example, every time we take a car, we can see the outside world and the things outside these cars are going backwards, this is the reference in our high school physics, this knowledge point, there is knowledge everywhere in life, you have to experience it with your heart.

As long as we have an eye for discovery, you must look more at the many phenomena in your life, whether it is natural or life, you also have to look at the stars at night, see their changes, you will also find light and heat in physics and some law problems. This knowledge is still present in our lives.

2. Learn to start with theorems.

You have to attach great importance to some theorems and some dead concepts and some laws, but you not only have to remember this knowledge from time to time, you have to learn how to use it, this is the key, smart children are using these formulas and then applying them to their own mistakes, from which to find the problem, you also have to do from a small mistake, you can review a lot of knowledge, it is really a double harvest, which is also the key to whether students can open up in high school physics.

3. Change incomprehension to very proficient.

Because there are many new concepts in high school physics, and there are also some nouns such as: potential energy, elastic potential energy, etc., you don't see these words that you haven't seen, and you don't like them, you know? As long as you have a deep understanding and look carefully, and then you look at some textbooks and some tutorial books, you can understand.

For learning, if you like this subject more, the better you will learn, maybe for various reasons to make you like this subject, maybe because of the teacher, some teachers grasp it tightly, you learn this subject very well, but some students just like this teacher and like this subject, if you change the teacher, you will not learn well, in fact, this is harmful to yourself.

It's getting closer and closer to the college entrance examination. Time is of the essence.

Ask for a tutor, ask for a mentor. Prescribe the right medicine. Tutoring is like a class, there is no use to bury it, and there is no targeting. Self-study is even more impossible.

You can't be left behind in the second year of high school. If you fall behind, don't try to catch up.

Science subjects should have the same amount of questions as the sea. It's about doing more questions.

I have had the same trouble as you, in my view of the oak seepage, that is, to take the class seriously (this is also a cliché) silver wheel, do more questions, and recommend you a reference book - five. Three, it's good, do one or two sets of review questions before the exam, it's a big help.

Study in advance before class, memorize the formulas, use the formulas flexibly, and use the backward method.
